Expected annual
$6.1M
One-time setup
$9.3M
Annual recurring
$6.0M
Personnel
29
Initial one-time capital and setup are approximately $9.0M driven largely by vessel purchases, buoy deployment, ROV/sensor procurement and a $5M salvage reserve. Annual operating costs are roughly $6.0M/year, dominated by staff wages, regular vessel/ROV operations, and ongoing research/monitoring.

⚡ Cost Scenarios
📊 Baseline (baseline) $6.0M/yr
87.5% probability / year
Normal year with no major incidents; regular operations, research, and maintenance only.
routine_operations scheduled_surveys no_incidents
🚨 Minor Incident $6.2M/yr
10.0% probability / year +$250K vs baseline
Single small commercial or fishing vessel sinks within exclusion zone requiring limited salvage, amnestics, and localized cleanup.

🚨 Major Breach $8.4M/yr
2.0% probability / year +$2.5M vs baseline
Commercial vessel loss or larger wreck that requires significant salvage, environmental response, and legal/compensation expenses.

🚨 Catastrophic Breach $14.0M/yr
0.5% probability / year +$8.0M vs baseline
Multiple-vessel incident or catastrophic containment failure triggering large-scale salvage, environmental remediation, heavy legal exposure and potential site rebuild.

📋 Confidence Notes
Analyst notes provide detailed line items and ranges enabling order-of-magnitude estimates, but many items have wide ranges (e.g., salvage/reserve size, frequency of incidents) and optional choices (helipad vs contract, buy vs lease) leading to moderate uncertainty.
